Fig. 12 is a fragmentaryfview showing a detail of the flexible supporting strip on the carrier and to which the chain thereof, is secured. Y y

Referring more particularly to Figs. 1V to 8, I provide a trench 11 beneath the stable partially represented at 10, said trench leading to a ramp 12 extending to a suitable structure 13 having elevated tracks 14 thereon spaced to permit material to drop between the tracks. A flexible carrier 15 is provided of any suitable form having wheels 16 adapted to travel in the trench 11 and on the ramp 12 and tracks 14, saidwheels turning on stud axles 172L on hangers 17 Adjacent hangers 17 may, as shown, be connected by links 18suitably secured as at 18a to adjacent hangers. n

A scraper 19 is arranged obliquely on the structure 13 between spaced vertical guide members 13a and at an elevation above the tracks 14 for the carrier 15 to pass, beneath the scraper. The front end 2O of the carrier is preferablyinclined and supported on a front wheel 16a at an elevation for the front edge of the end 20 to pass beneath the scraper 19 to slightly raise the latter and insure a scraping engagement of its lower edge with the top surface of the carrier to deflect the manure therefrom laterally permitting it to drop into a wagon (not shown).

On the carrier 15 is a flexible chain rack 21, certain links of which have brackets or lugs 21a secured to a longitudinal flexible strip 21b ranging lengthwise of the carrier adjacent to the center thereof so that the chain rack y21 is at the longitudinal center or approximately so. Said rack 21 is engaged by sprocket .wheels 22 on transverse shafts 23 which are provided with sprocket pulleys 24 at one endover whichV a chain 25 runs connecting up. the two shafts; one shaft 23 is a driven shaft and is driven from any convenient source of power, there being provided for the purpose in the illustrated example, a worm wheel 26 on the shaft engaged by a worm 28 on a shaft 27, here shown as having a universal joint 29 and extending into the stable 10 where it is provided with pulleys 30 adapted to be driven by any convenient power, such for example, as a lgas engine (not shown) with which stables are now usually equipped.

The scraper 19 is provided with vertical krods 31 extending downwardly therefrom vided to regulate the height of the lower edge thereof, said means preferably consisting of cams* 35, 35a near each end of the scraper. @ne cam 35 is rigid with a lever 37 lulcrumed at its lower end as at 36 on a bracket 38 or other support on the structure 13, said lever being provided with a latch 39 adapted to engage an arcuate rack 10. The opposite cam 35 is rigid with lever 42 tulcrumed at its lower end as at 51 on the structure 13, said lever l2 being connected by a link L14 with the lever 37 between the ends of the latter as at 413, and the arrangement being such that the scraper 19 resting on the cams 35., 35at may be raised or lowered with the rocking of the lever 37. A depending scrapert is provided on carrier 15 at the rear end to scrape the bottom o' trench 11, the scrapings being adapted to be carried through said trench and over the ramp 12 to the structure 13 to drop between the tracks 14': into a wagon or onto the ground'. Also, side sclrapers 46' are provided on said carrier near each endat the sides to project beyond the side edges tor scraping the side walls of trench .11. Short vertical rods or pivots 117 carrying said scraper-s 16 extend downwarcUy through the carrier 15 and are provided with lateral arms to be 'connected with one end ot a retractile spring 49, the opposite end of the spring being secured to lined pins or the like at the under side of the carrier.

In Fig. 9 avcarrier 151 is'adapted to run in a trench 11EL lbeneath thev stable 10a and over a bridge 12aforming a continuation of said trench, outside the stable, and pivf otedas at 57 to swing in a vertical plane for permitting the wagon to be driven beneath the bridge. The arrangement is designed particularly for side-hill land and the bridge 12 leads to a structure 13b having ixed tracks 14;, The carrier 15a is provided with wheels 16" and the front end 2Oil ot said carrier is supported inclined by a small wheel 16c to wedge itself beneath the scraper 19, which scraper is arranged and equipped as previously described. The supporting rods o't the scraper as well as the springs thereon and means for raising and lowering the scraper having been fully described, the description need not be repeated in connection with Fig. 9. The bridge 12a is raised and lowered by suitable means such as a rope 5S secured to the front endl of the bridge as at 58a and running over a sheave 59 on stable 10a, the rope in practice extending to any convenient point that it may be grasped and made fast after the bridge has been positioned as desired. The

rear end of carrier 15 is provided with a tail board 6a hinged at its lower end as at 51 to the rear end of the carrier. A. hanger 53`on the tail board at the outside to be swingable therewith, is pivotally connected at` its lower end to a horizontal pin 52 eX- tending forwardly beneath the carrier through a guide bracket 54 said pin having a spring 55 coiled about the same and bearing against said bracket 54: and against collar 5601i the pin, the arrangement being such that as the tail board 46 strikes the scraper 19, it mayV turn on its hinge 51, the spring 55 serving to restore the tail board to its vertical position. A haul rope is secured to the front end of the carrier` 15'n` and be hitched by any suitable means (not shown) to a draft animal for-hauling thecarrier. A return rope 6()d is secured as at 60e tothe rear end of the carrier 15", and passes over `suitable pulleys 60H 60g.

In the form shown in Fig. 11 the carrier 15b has wheels'ld adapted to travel in the trench 11b beneath the stable 10b and onto a ramp 12b which is supported between the said trench and the outer 'structure 13C, supporting the trackways '111b and scraper 19. A haul rope 60a is connected with the front end or' the carrier 15b and is adapted to run along the ramp 12b and through the structure 13d to he hitched to a draft animal for the forward haul of the carrier tov said structure. A second haul rope 60b runs over suitable guide pulleys such as a pulley l61 on ramp 12b, pulleys 61a on structure 13h and the pulley 61b in the trench 11b near the rear end thereof, said haul rope 60b being secured at its rear end as at 61c to the under side of the carrier near the rear end.V Said carrier is provided with a rigid end board 4Gb at the rear end and vhas a depending scraper a5. T he front end-20b of carrier l15b is supported inclined by a low front wheel 16e.

As seen in F ig. 12 the strip 21? is formed with ker-fs 21d as one means of producing a iiexible strip. f d

To tighten the chain 21 where it engages the sprocketwheel 22'I'employ tighteners at opposite sides ot' said sprocket wheel and this may consist as shown of standards 65V having their upper ends 66 extending laterally over thechain 21 to bear down upon the same. Said standards are secured in the present example to Cross bars 67 on the frame 13 by a slot and pin connection, there being slots 68 in said standards and pins or bolts G9 securing the same to bars 67.

I Ywould state in conclusionthat while the illustratedV examples constitute practical embodiments of my invention, Ido not limit myself' strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.;

Having thus described my invention, I claim':

1. An apparatus of the class described including'a scraper, a carrier adapted to travel beneath said scraper, and means yieldingly supporting said scraper, the forward end of said carrier presenting a dip to eXert a wedging action against the lower edge of the scraper.

2. An apparatus of the class described including,` a structure, a runwayr leading to said structure, a carrier movable along said runway to and from said structure, and adapted to receive material at the top surface thereof, means on said structure adapted to dislodge material from the topr of the carrier, and a scraper. on said carrierV at the underside adapted to scrape the bottom of said runway.

3. An apparatus of the class described including a structure, tracks thereon spaced` rear end to scrape said runway and drag the scraped material to said tracks to permit the material to drop between the tracks, and scraper means on said structure above the tracks beneath which scraper said carrier is adapted to travel for the scraping of the material troni the top surface of the carrier, said scraper being adapted to scrape the material laterally fromsaid structure.
